When the layers in the shear flow become wrinkled the motion grows complicated, especially when the wrinkles roll up into whirls .
当剪流中流体层开始起皱，尤其是皱褶卷曲成旋涡时，运动就复杂化了。
As the basis of stochastic torsional analysis , a stepped thin - walled beam model with complex cross - sections of arbitrary shapes ( open , closed or mixed ) is established in this paper , which takes into account the effect of secondary shear flow resulting from warping restraint
摘要具有复杂断面形状的阶梯精密梁模型作为扭转随机分析的基础，可以计及翘曲约束引起的二次剪流。
